• What is the cause and solution for SAP error message C1324 - Only "," or "." can be used as a decimal point ?

  The SAP error message C1324, which states "Only ',' or '.' can be used as a decimal point," typically occurs when the system encounters a numeric input that does not conform to the expected decimal format. This can happen in various scenarios, such as when entering amounts in financial transactions, data uploads, or configuration settings.
  Cause:
  
  Incorrect Decimal Separator: The error usually arises when the decimal separator used in the input does not match the expected format defined in the user settings or system configuration. For example, if the system is set to use a comma (,) as the decimal separator, but the user inputs a period (.), or vice versa.
  Regional Settings: The issue may also stem from the regional settings of the user profile or the system, which dictate the expected format for numbers.
  Data Import Issues: If data is being imported from an external source (like a CSV file), and the decimal separator in that file does not match the expected format, this error can occur.
  
  Solution:
  
  
  Check User Settings: 
  
  Go to the user profile settings in SAP and check the "Decimal Notation" settings. Ensure that the decimal separator matches what you are trying to input.
  You can access this by navigating to System > User Profile > Own Data and then checking the "Defaults" tab.
  
  
  
  Adjust Input Format: 
  
  When entering numeric values, ensure that you are using the correct decimal separator as per your user settings. If your settings expect a comma, use a comma; if they expect a period, use a period.
  
  
  
  Review Regional Settings: 
  
  If you are working in a multi-national environment, ensure that the regional settings of the SAP system are correctly configured to match the expected formats for all users.
  
  
  
  Data Import Configuration: 
  
  If the error occurs during data import, check the source file for the correct decimal format and adjust it accordingly. Ensure that the file uses the same decimal separator as defined in the SAP system.
  
  
  
  Consult Documentation: 
  
  If the issue persists, consult SAP documentation or your system administrator for further assistance, as there may be specific configurations or patches that need to be applied.
